Opal8A industrial switch 8x100M RJ45

Opal8A – Compact unmanaged Fast Ethernet switch with robust construction

The Opal8A is an unmanaged DIN-Rail switch with 8 Fast Ethernet RJ45 ports supporting 10/100Base-T(X), designed for reliable Ethernet connectivity in industrial applications. Thanks to its compact dimensions, metal housing and fanless design, it is suitable for installation in demanding industrial environments, such as automation and control systems.

Key Features

• Ports: The switch features 8 RJ45 ports supporting 10/100Base-T(X).

• Construction and durability: The metal housing with IP30 protection is designed for industrial use. Natural convection cooling without a fan (fanless design) ensures quiet operation without moving mechanical parts.

• Power supply: The switch supports 12–48 VDC or 18–30 VAC and features redundant power inputs. Overload and reverse polarity protection are also provided.

• Features: The Opal8A supports QoS for efficient network traffic handling and allows broadcast storm protection to be enabled or disabled using a DIP switch.

• Operating temperature: The switch is available in a standard version with an operating temperature range of -10 °C to +60 °C (Opal8A-E) and a wide-temperature version with a range of -40 °C to +75 °C.

• Low power consumption: The switch has a power consumption of less than 3 W.

• Installation: The switch can be easily installed on a DIN rail or panel.
